5 Seconds of Summer

Dates: July 17th-September 13th

Opener: Hey Violet

Why You Should Go: 5 Seconds of Summer grew as a band by opening for One Direction across the world for two summers straight. The Australian pop-punkers have since found their own way, riding high on the success of their smash single "She Looks So Perfect" and self-titled debut. Now the quartet — who are all between the ages of 18 and 21 — have embarked on their first tour as headliners and are looking back to the Eighties for some arena-rock inspiration. "[I've] been watching a lot of [VH1's Behind the Music]," reveals lead singer Luke Hemmings. "Like the Guns N' Roses one, the Poison one, Bon Jovi. I've been looking to those bands and what they do with stages, like how Axl Rose will command a whole stadium." For the Rock Out With Your Socks Out Tour, Hemmings notes that their vibe is mostly to create a sense of intimacy with everything from the setup to the lighting. "It's an arena-level theater show."
